HAND-FAN.

Specification of Letters Patent.

Patented A11 26, 1919.

Application filed September 24, 1918. Serial No. 255,527.

To all whom it may concern Be it known that we, GEORGE FIscI-InmN andLOUIS NEWMAN, subjects of the King of Hungary, and residents of the cityof New York, in the county of New York, and Bronx, respectively, andState of New York, have invented certain new and useful Improvements inHand-Fans, of which the following is 'a specification.

The present invention relates to improvements in fans, and moreparticularly to a toilet-fan having a plurality of blades.

The main object of the invention is to provide a simple, efiicient anddurable handoperated fan of this character, the blades of whichcan berapidly rotated to set up an ail current, and which requires littleexertion for its operation.

Another object of the invention is to provide a fan, consisting of aplurality of telescoping sections and having blades which can be foldedor collapsed, whereby the device can be conveniently carried along inthe pocket or hand-bag of the user.

A further object of the invention is to provide a fan of the typespecified which can be manufactured on a commercial scale, or, in otherwords, one which is not so diillcult to make as to be beyond thereasonable cost of such a contrivance.

l/Vith these and other objects in view which will more fully appear asthe nature of the invention is better understood, the same consists inthe combination, arrangement, and construction of parts hereinafterdescribed, pointed out in the appended claims and illustrated in theaccompanying drawings, it being understood that many changes may be madein the size and proportion of the several parts and details ofconstruction within the scope of the appended claims without departingfrom the spirit or sacrificing any of the advantages of the invention.

One oi the many possible embodiments of the invention is illustrated inthe accompanying drawings, in which Figure l is a front elevation of afan con structed in accordance with the present invention; Fig. 2 is asimilar elevation of the same, in its folded state; Fig. 3 is a sectiontaken on line 33 of Fig. 2; Fig. 4 is a section taken through the foldedfan blades and part of their actuating mechanism, on a larger scale;Fig. 5 is a section taken on line 5-5 of Fig. l-; and Fig. 6 is asection taken on line 66 of Fig. 5.

In the drawings, the numeral 10 indicates the casing of the contrivance,comprising two tubular sections 11 and 12, the former being adapted totelescope into the latter. The section 11 is closed at its upper end bya head 13 and the section 12 at its lower end by a head 14. This casingmay be of a size suitable to constitute the handle of the fan and alsothe means for inclosing the actuating mechanism of the fan bladesthereof. In the section 11 is rotatably mounted near its upper closedend a horizontally disposed tubular arbor 15, one end of which extendsthrough the casing and is provided, outside of the said casing, with acircular flange 16, having four outwardly bent equidistantly spacedprojections 17 at or near its periphery, for a purpose hereinafter to bedescribed. Through this tubular arbor extends a spindle 1.8, the frontend of which projects beyond the flange 16, while the rear end extendsbeyond the rear end of the tubular arbor and is disposed outside of theeasing. To the rear end of the spindle is fixed a knob 19, and betweenthis knob and the easing is disposed a washer 20, that is drawn over thesaid spindle. Between the washer and the knob is inserted a spring 21,coiled upon the said spindle, for a purpose hereinafter to be mentioned.The front end of the spindle 18 is reduced, as clearly shown at 22, andto this reduced end are pivoted four fan blades, 23, held upon the saidspindle, for instance, by a nut 21, the threads of which mesh withthreads on the reduced end of the spindle. The inner ends of theseblades are disposed between the projections 17 above referred to, saidprojections serving to space the said blades and also as a means fortransn'iitting the rotation of the tubular arbor 15 to the said blades.The spring 21, on the other hand, serves to keep the blades between theprojections 17.

The driving mechanism comprises a bellcrank lever 25, that is fulorlnnedat 26 to the casing section 11, and extends through an opening 27 in thesaid section through the casing. The outer free end of the bellcranklever is provided with a linger piece 28, while its inner end isconnected by a link 29 with a crank shaft 30, the latter being rotatablymounted in .the casing section 11. The crank shaft is connected with thetubular arbor15 by a train of" gears 31, the ratio between the gears ofthe Stud train being such that one revolution of the crank shaft resultsin a great number of revolutions of the tubular arbor and the bladesconnected therewith. A spring 32, bearing against the bell-crank leveranda stop 33 within the casing section 11, serves to shift thebell-crank lever'to its outer position, as will hereinafter appear.

The casing section 12 is provided with a longitudinal slot 34, throughwhich the bell-- crank lever 25 projects.

The operation of the device is as follows :IVhen the fan is to be placedinto a pocket or small satchel, the spindle 18 1S forced against theaction of the spring 21 in the direction of the arrow shown in Fig. 3 ofthe drawings, whereby the blades 23v of the fan are disengaged from theprojections 17 on the flange 16 of the tubular arbor 15. They are thusadapted to be folded substantially parallel to the longitudinal axis ofthe casing 10 and engage with two neighboring projections 17 when thespindle 18 is released. The tubular sect-ion 11 of the" handle is thentelescoped into the section 12 thereof, the slot 34 in the lattersection permitting. of such operation.

To prepare -h-e fan for use, the blades are brought into the positionshown in Fig.

1 of the drawings, and the sections of the handle extended; The fan is.held in on hand of the user, who presses the thumb against the fingerpiece 28, forcing the same inward against the action of the spring 82,the latter causingthe lever to move outward when the finger piece isreleased. In

this manner the crank shaft is rotated, the fan blades through the trainof gears. The blades ro-:

its rotation being imparted to tate thus at a high speed and set up acooling current of air. To overcome the inertia of the crank shaft, itmay be necessary, when starting the operation of the device, to turn thefan blades with one hand while actuatingthe bell-crank lever 25 with theother hand, until said blades act as a fly wheel for the said crankshaft.

The device is easily operated by the movement of one of the fingers ofthe user, or in. other words without useless exertion, which would heatthe body and tire the person using the fan.

It is obvious that, while herein a particular'numberof fan blades hasbeen referred to, any other number may be used without departing fromthe invention.-

In a fan, the combination with a casing comprising a plurality oftelescoping tubular sections, of a tubular arbor rotatably mounted inone of said sections, one end of said arbor extending through the saidcasing sectionand being provided with longitudinalaxis of said casing bydisengagmg the same from said pro ections, a bellcrank lever pivoted tosaid casing and extending therethrough, and a driving connection betweensaid bell-crank lever and saidtubular arbor.
